My invention relates to an operation chart and indicator for carryingout a process hav ing diferentsteps of progression during ytheloperation. f y i l v 5,-' While'theinvention is intended for generaluse itis especially well adapted for use Y in-connection with a laundryclothes washer, commonly referred to in the tradeas a Wash yingwheeL fv.10 ItV is wellv known y that fromk thetime'y clothes are placed in aWasher until the far the operation has proceeded.

clothes `are removed they arefsubjected to different processes Vduringthe washingr oper-V c ation. f. During this operation the height of "15the Water in the washer is changed several'y j times as well as thetemperature of the water and for each step or process during the Washingoperation the washer isoperated a prede-v l. termined period .of time.It 1s customary "zofforan operator of awasherto have an alarm cclockwhich isset at the beginningof each step during i the washingoperation and t sounds an alarm yat the end of the 'respectivestep whichis fora predetermined period of The number of steps during a washwashingand particularly when `he has a num-5 f ber yof washers to look after.yFurthermore, y the operator must remember ywhether the articles beingwashed are' of alight yor dark lcolor and if the articles being Washedvare personal clothes, such as hotel guest work,

' hotel flaty work', family wash, overalls,

or of any trade'. Y

The invention as illustrated is designed other classification used bythe for use in connection with a laundry washerV and includes anoperationy chart onfwhich appears the dif'eernt stepsfto be Vperformedvduring ya washing'operation, the height of the "water in thewasher,`the temperatureof `the water andthe number yof minutesthe-washer is to be operated duringgeachstep ofthe op eration. Theinvention further provides an indicator that'may be manually setltoindi-A cate the current step in-a washing operation ing operation arevaried dependingon the kind of kclothes ,being washed. Due to the 1931.seria1No.544,151. y

ktogether with cut-outindicators for cer-` tainof the steps duringctheoperationfor dife ferent classes: of work.l n

By Vthe use of this invention an operator by` looking at thechart maytell'at a 'glance the" different steps to followin carrying out a givenwashing operation and the indicator.- will denote the current step inthe operation so thatvoperators maybe changedduring a, washingoperationwithout confusion as to the kind ofclothes being washed or as tov how Tothe above end, generally-stated, the inventionl consists..ofcombinations of devices hereinafter describedand defined inthe claims. v

I y the center of the panel is a'sectionaly washing chart'made upof amaincard 11 and a plurality of secondary cards 12. The main.. cardl 1lis removably mounted in a main?L holder 13a-nd the secondaryzcards 12are removably and individually kmounted insecondary holders 14; .Theseholders 13 andfvl are secured to the panel 5, vertically spaced, the onebelow the other, with the main holder?4v 13 at the top. Y f 1 f Thefollowing indiciajappears' on the main card 11, readingfromthe'leftftothe right:

Water, and Mins/to "runy The :abbrevia the several viewsp theAnovel-"devices and I 20 .6 isan .indicator comprising a -30 .17, readingof course, are

tions Temp and Mins,

Printed for temperature and minutes, on the secondary cards 12, readingfrom the top down, are the different steps or processes 5 to be followedin Washing clothes. The secondary cards 12 also have printed thereon ina vertical column under Height of Water numerals indicating the heightof water in the washer for each step in the operation. A vertical columnof numerals also appears on the cards12 under.'lf."emp..of Water-indicating the temperature of the Water in each of said steps, andunder Mins to run isla vertical column of figures representing the 15number of minutes for each step of operation. It rwill benoted .thatVeach secondary \mrd;12`ismade in section' so .that the .indicia maybechanged, at will.

-Qn-the right handendrportion.oi `the panel horizontal row of `holes'liin said panel/for each vsecondary 'holder 14.

Anindicator plug 18s-adapted to be placed 4in any one offthe. holes-151is 4attached by a cord 19 to the panel 5. The vertical rowof :holes:115 in whichftherindicator plug 18 is placed indicates the type orclass of clothes iiag-washed while the'horizontal row indicates .thecurrent step in the washing; operaztion.
